The Internet of Things (IoT) has brought waves of innovation opportunities into the smart buildings driven by the need for occupant centric, energy efficient, healthy, and productive buildings. The technology shift to IP-based communications, interoperable protocols, data standardization, advancement in machine learning (ML) and integrations with conversational agents will propel the next generation of buildings to be actually “smart”. The building occupants will not only enjoy the safety and comfort of healthy buildings but be more productive and able to talk to building bots to provide real-time feedback. Meanwhile, the building owners will be able to provide energy efficient greener buildings that adhere to net-zero green-house gas emissions and comply with local and country guidelines.
